Borosilicate glass - Wikipedia, the free encyclopedia In addition to the quartz, sodium carbonate, and calcium carbonate traditionally used in glassmaking, boron is used in the manufacture of borosilicate glass. Borosilicate glass has a very low thermal expansion coefficient, making it a popular material for objects like telescope mirrors, where it is essential to have very little deviation in shape. Borosilicate glass is sometimes used for high-quality beverage glassware; Bodum, Inc. markets a line of French coffee presses and double-walled beverage glasses made of borosilicate, lending them increased durability and microwave/dishwasher compatibility. en.wikipedia.org /wiki/Borosilicate_glass   (396 words)

Solstice Glass - About Borosilicate Glass Borosilicate glass is a very unique and specialized variety of glass. Chemically speaking, borosilicate glass substitutes boron oxide particles in place of the soda and lime particles found in soft glass. Also, because of the chemical composition of borosilicate glass, different precious metals such as silver and gold may be used to color the glass in some very unique and amazing ways. www.solsticeglass.com /about_borosilicate_glass.html   (273 words)

Electronic package comprising aluminum nitride and aluminum nitride-borosilicate glass composite - Patent 5102749 Borosilicate glass also has a significantly lower dielectric constant than AlN so that the dielectric constant of the resulting composite is low. Initially, a homogeneous blend of AlN particles and borosilicate glass particles is prepared by wet or dry grinding, as hereinafter described in Example 1. Initially the borosilicate glass is in particle form, for example, when first mixed with AlN and when made into a sheet with AlN. www.freepatentsonline.com /5102749.html   (6624 words)

Scientific Laboratory Glassware: Lab Beakers, Erlenmeyer Flasks, Graduated Cylinders, Test Tubes, Burets   (Site not responding. Last check: 2007-10-21) These borosilicate boiling flasks (florence flask) are made to ISO 1773 and are highly resistant to breakage due to heating or chemical attack. A borosilicate glass graduated cylinder should be used instead of other materials such as polypropylene and TPX if you are going to use oxidizing materials and certain hydrocarbons which can cause plastic to cloud. Borosilicate glass will withstand a fair degree of thermal shock but unless your intent is to see if you can make it crack, don't toss recently heated glass into a cold water bath. www.indigo.com /glass/glass.html   (777 words)

Casting the First 8.4 Meter Borosilicate Honeycomb Mirror for the Large Binocular Telescope This paper deals with the design and fabrication of the borosilicate glass honeycomb substrates for the primary mirrors which are being fabricated at the University of Arizona's Steward Observatory Mirror Laboratory. The glass honeycomb sandwich structure is formed by melting chunks of borosilicate glass into a mold which is the negative of the desired structure. Borosilicate glass is used for the production of these mirrors because it is relatively inexpensive and it can be readily cast into the desired honeycomb structure. medusa.as.arizona.edu /lbto/tech/mirror98.htm   (2992 words)

TCLP Leaching Prediction from the "THERMO(TM)" Model for Borosilicate Glasses The studies indicated that either borosilicate or soda-lime-silica glass (SLS) formulations could be used, with at least a 75% waste (sludge) loading on a calcine oxide basis. The borosilicate glasses were shown to meet the hazardous waste leaching requirements in place at that time [4]. Additional treatability studies were conducted in 1993 on a wide range of borosilicate and SLS glasses to optimize the glass formulation to be used for the stabilization of the M-Area sludge [5]. sti.srs.gov /fulltext/ms2001925/ms2001925.html   (2927 words)
